'Be it knownthat 1 JOHN Annnizson,

, a citizen of the United States, residing at Geneseo, in the countyot Henry and State of Illinois, have invented a new and useful Attachment for Bearings, of Which'th'e following is a specification.

It is the object o f this invention to provide-novel means. whereby a nuton' a bolt "may be rotated to take upwear in the part throughwhich the :bolt passes. The invention aims to provide novel means whereby a spring which imparts rotation to the bolt, as

aforesaid, maybe wound up and held under tension.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

With the above and other which Will appear as the description proceedsgthe invention resides in the combina- I tion and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in.

the precise embodiment of the invention shown can be made withoutdeparting from' the spirit of the invention.

In the accompanying drawings Fig. 1 shows in elevation a device constructed in accordance with the invention, the same being assembled with the bearing,

and the parts of the bearing appearing in section. Figure 2 is a plan showing one of the nuts and the rotatable member which is I journaled thereon; Figure 3 is a plan showing the other of the nuts; Figure 4 is a fragmental section showing a portion of the bolt and the nuts; Figure 5 is a view similar to Figure 1 but showing a modification; Figure 6 is a plan disclosing one of the nuts and a rotatable member; Figure7 is a plan disclosing the rotatable member; Figure 8 is a plan depicting one of the nuts; Figure 9 is a section showing the structure disclosed in and the head ofthe nut.

A coil spring 39 is idiss' posed around the tubular nut36, the spring having hooks 40 at its ends, one book being engaged with one of the notches 34 of one of the arms 33, and the other hook 40 being the wrench engaged with the notoh ;38 in head 37 of :thetubular nut 36. A tie, such a plate is jour- A tubular nut as a piece ofwire, denoted by. the numeral 41 is engaged in one of the openings 35,; the tie being connected by an'anchonwhichmay be in the form of a pin 42, to the part 26.

The nut 36 is rotated until it bearsag'ainst i the neck 30 of the the nut; 29, When loosespring 39 reactsand by turning nut 36 rotatesithe bolt 27, the parts 2 5. and 26 being brought together because thebolt is threadpart 26. Passing to Figures 5, 6, 7, 8 and 9 the numerals 45 and 46 designate twoflmembers through which nut 29, the spring39 be- .ing. put under tension, the nut :36 serving .as a lock nut for Eness occurs between the parts 25 and 26, the

passes a bolt 47 having a, head 48 engaging the member 45- "The bolt ed at 44 with a left hand thread into the 47 has a thread 49 on which is mounteda tubular nut 50 having a wrench head 151] cooperating with the member 46. Thereis a notch 52 in the edge of the wrench head 51, as shown in" Figure 12. The numeral 53 denotes a nut on the threaded part 49. of the bolt, the (nut 53 having-a neck 54 on which a washer or ring 55 is fitted tightly. A member 56 is rotatably mounted on the neck 54 between the washer 55 and the body portion of the nut 53, the rotatable member having a knurled flange 57 whereby rotation may be imparted and is provided, as shown 1n Figure 11 with the key hole slot 59. The numeral 60 marks a coil spring surrounding the-tubular nut 50. Thespring 60 has hooks 611 at its ends.

'The'member 56 has notchesl58 in its edge ing engaged in the key hole slot 59 ofthe' rotatablemember 56. The nut-53 has .a side recess .62 wherein is located a tie 64t,.which may be a piece of wire. 'One end 65 of the tie is engaged as shown in Figure 10 with the nut 53. The other end 66 of the'tiemay be passed into any of the notches 58 in the rotatable member. A. lock nut 67 is mounted on the threaded portion of the bolt and I bears against the nut 53.

r The member56 may be rotated to put the spring 60 under tension, is secured in the sprin the wire or tie .64

and after :a tension may be engaged .in the appropriate one of the notches 58. The lock nut .67 then is tightened-down on the nut :53 iand, obviously, the tension willbe held in .the'sprin-g, the spring serving toyrotate the nut 50 and-to advance the same with respect to the member 46 as soon as anylooseness occurs. Referring to Figures 10 and 11, a rotatable member 70 is shown and is provided modification, I vided along the line73 and is provided with I outstanding fingers 7 4 having notches '7 5 constitute a u'sefulindex,

with arms 71 having openings 72. In-this the rotatable member 70 is diin their edges. A bendable strip 7 6 may be used to connect the parts'74, the strip being engaged in the notches 7 5 and being turned over on the j parts74e, as indicated at 77 in Figure 11.

It is not possible to show all of the various forms which the inventionmay take, nor has anyattempt been made to show all of i the applications to which the invention may be put. The forms shown will, however, skilled in theart, to many other applications which will suggest themselves without difdirecting a person what independent of theanutyiand bolt for holding :said member releasably against 1 rotation;
